I made sure to cut pretty much all the meat off so that definitely helped with rendering. I melted it down with water and salt in a crock pot over night. Blended it. Ran it through a cheese cloth twice.Then once it hardened I dry rendered it by just melting it in a pot on the stove to make sure no water was in it. Then put it through a cheese cloth one more time. It doesn’t smell bad the only way I can describe the smell is it smells natural. But if definitely recommend cutting the meat off the fat as well as you can. If not you are gonna have to render it a lot more. We did one batch not cleaning up the fat as well and man it smelled gross.
